Fig. 4From: A two-stage deflection system for the extension of the energy coverage in space plasma three-dimensional measurementsTransmittance as a function of the ion beam energy (EBEAM) and the elevation angle (red: simulation, blue: laboratory experiments). Contours are plotted for 10, 50, and 80% of the peak value. Four cases correspond to the trajectories in Fig. 3. The beam energy is normalized by the voltage of the electrostatic analyzer (VESA). The deflector voltages (VDFL) are varied with a fixed VDFL/ VESA ratio following Table 1Back to article page
